A newsletter by Nikola Balić

Close Supervision

Look closer. Make it work.

The letter on keeping agents useful. Every other Tuesday I send one idea I have tested on the bench, three signals worth your time, and one question. Replies come straight to me.

What lands in your inbox

  • The idea. One argument with a concrete example, usually an optimization diary: what I ran, what broke, what moved the needle.
  • Signals. Three to five links, each with a take. No link goes in without a comment.
  • From the bench. What I am building or measuring in Close Supervision Labs right now, with numbers when I have them.
  • One question. A real one. The best reader replies show up in the next issue, with credit.
